Soil is composed of organic matter (decomposing plants, animals, and microbes), biomass (living plants, animals, and microbes), water, air, minerals (sand, silt, and clay), and nutrients (nitrogen, carbon, phosphorus). [4] For optimal plant growth, a proper carbon to nitrogen ratio of 20–30:1 must be maintained. [3]
The horizontal logs can float, but are anchored by the posts. Newly planted trees will eventually stabilize the soil. The fallen trees with roots jutting into the stream are intended to enhance wildlife habitat.

Assisted natural regeneration (ANR) (also termed managed regrowth) is the human protection and preservation of natural tree seedlings in forested areas. Seedlings are, in particular, protected from undergrowth and extremely flammable plants such as Imperata grass. Though there is no formal definition or methodology, the overall goal of ANR is ...
China committed to plant and conserve 70 billion trees by the year 2030 as part of the Trillion Tree Campaign. [80] The Jane Goodall Institute launched the Million Tree Project in Kulun Qi, Inner Mongolia to plant one million trees. [81] [82] China used 24 million hectares of new forest to offset 21% of Chinese fossil fuel emissions in 2000.
Regenerative agriculture is a conservation and rehabilitation approach to food and farming systems. It focuses on topsoil regeneration, increasing biodiversity, [1] improving the water cycle, [2] enhancing ecosystem services, supporting biosequestration, [3] increasing resilience to climate change, and strengthening the health and vitality of farm soil.
The new growth of seedlings and community assembly process is known as regeneration in ecology. [ 1 ] [ 2 ] As ecological succession sets in, a forest will slowly regenerate towards its former state within the succession ( climax or any intermediate stage), provided that all outer parameters (climate, soil fertility availability of nutrients ...
